 I doubt this box will do DMA, ever. AFAIK the chipset just does not
 support it.

Apparently drivers/ide/setup-pci.c forces it to use DMA as there's a switch in
which certain chipsets are forced to use DMA, while the default handling is to
disable it.

Thanks for your useful reply!

With friendly regards,
Takis

Bug#395031: Kernel complains about DMA

2006-10-24 Thread Panagiotis Issaris 
Package: kernel-image-2.6.8-3-386
Version: 2.6.8-16sarge5

When booting the abovementioned kernel on a friends laptop, it shows errors when
trying to initialize the IDE controller. When showing the errors, it waits for
quite some time, increasing the boottime with about a minute (raw guestimate).

The laptop is a Dell Lattitude xpi cd p150st and it is running the current
Debian stable.

For now, I've compiled a 2.6.19-rc3 kernel without DMA support which boots fine
(and fast). I'm about to test a 2.6.19-rc3 kernel _with_ DMA to see if the bug
has been fixed sometime after the 2.6.8 kernels.

thanks for your tests, please file the bug upstream in
bugzilla.kernel.org with dmesg lspci -v attachment.

please let us know the upstream bug nr.

Please try the 2.6.18 from backports.org - that is what we plan to
ship in etch.
